Find the flow rate Q when the flow velocity distribution u (m / s) in the pipeline with radius R (m) as shown in the figure below is expressed by the following equation as a function of the distance y (m) from the inner wall surface. However, U is the maximum flow velocity (m / s) in the central axis of the pipeline, and the flow velocity distribution u is symmetrical with respect to the central axis of the pipeline, and 0 ≦ y ≦ R.
